Porsche has brought back six-cylinder power to the standard 718 Cayman and Boxster line-up in the form of new GTS 4.0 variants. They’re available to order now, with first deliveries due in March, and are priced from £64,088 for the Cayman GTS 4.0 and £65,949 for the Boxster version.

Replacing the outgoing 718 GTS models, which used a 361bhp 2.5-litre flat four engine, the new GTS 4.0 has – as the name suggests – the 4.0-litre flat six motor first introduced on the Cayman GT4 and Boxster Spyder last year. Unlike those track-focused cars, the new GTS models “place particular emphasis on everyday driving pleasure”, Porsche says.

For the GTS 4.0, the engine is detuned from the 414bhp of the GT4 and Spyder to 395bhp, which is produced at slightly lower revs than the peak power of those cars. The torque figure remains unchanged. 

The quoted 0-62mph time for both the Cayman and Boxster GTS 4.0 is 4.5sec – just one-tenth down on that of the GT4 and Spyder. Top speed is put at 182mph, a 6mph reduction on the GT4’s. 

The redline for the GTS engine is 200rpm lower than the GT4 motor’s, topping out at 7800rpm. However, both new models continue to use the sports exhaust system from the GT4 and Spyder. 

The two GTS 4.0 models come solely with a six-speed manual gearbox at launch, although an automatic option is expected at a later date. Features such as adaptive cylinder control, which shuts down one of the two cylinder banks at low engine load, helps the new motor achieve 25.9mpg under WLTP rules, and a CO2 figure of 246g/km. 

The 718 GTS 4.0 models feature Porsche’s Active Suspension Management system, which drops the ride height by 20mm over the base Cayman and Boxster. Also included is a torque vectoring system with a mechanical limited-slip differential, the Sport Chrono pack with active drivetrain mounts, and an upgraded Porsche Track Precision App.

Porsche 718 Cayman

Can the best sports coupé of the decade absorb a contentious new engine?

Back to top

Reining in the standard 20in black alloy wheels is a brake system upgraded from the regular models’ and marked out by cross-drilled discs and red calipers . A ceramic-composite set-up is an option. 

Exterior changes for the new GTS pair include dark contrast detailing on the spoiler lip, air intake and lower rear bumper, as well as tinted front and rear light lenses. Inside, there’s liberal use of Alcantara, including on the Sports Seats Plus, and a number of personalisation options.

And £65k seems like a decent price for what could be the best car Porsche makes.

Out with the turbo 4 pot. In with the NA 6 pot. lets hope where Porsche lead, others follow. Better still, you have to have a manual box! (i had to check it wasnt April 1st!)

Brilliant news, six cylinder engine, manual gearbox and adaptive damping; exactly how I'd spec a sports car. Fills the whole in the market left by the f-type going v8 auto. Now, which vital organ can I sell to raise £65k?

16 January 2020

I knew it would happen sooner or later, the turbo charged 4 cylinder sounds awful (even though its quick). Now the 718 has that fantastic 6 cylinder sound to go with the amazing chassis.

This decision surely must be a recognition by Porsche that an engine, and it how it goes and sounds, is probably the most critical part of a sports car, especially a higher spec model like the GTS. The four cylinder engines aren't simply anywhere as good in almost every area bar emissions over the flat-6s they replaced. They even weigh more too I believe.


In terms of power output, the GTS models seem to have seen the most power increaseses of any version of the current Cayman and Boxster, starting off with around 330bhp with the original 3.5 flat 6, then 361bhp with the 2.5 flat four and now just shy of 400bhp with the 4.0 flat 6. More interesting is that the GTS version of the (991) 911 had 444bhp but for a price that was just over £30k more than these latest GTS Cayman and Boxster. Porsche is going to have to give the next 911 (992) GTS a lot more power and go to justify what will inevitably be around a 50% higher price over these new GTS Cayman and Boxster models!

Joy of Joys, I thought at one point they were going for a 1.0 3 pot Hybrid. lol

That's the best looking green car, EVER!

Couldn't agree more. The Alpine A110S is around £10k cheaper than the Cayman GTS and the Supra, with a still healthy 340bhp, starts from around £15k less than the Porsche. Porsche are pricing their cars as high as they are because they think they can, as if the Porsche brand is at a level to warrant a huge premium over many rivals.

It may have less cylinders and less power, but I'd plump for the superior Alpine A110S without hesitation. And with the Alpine being so much lighter that the Cayman GTS, it handles and steers better and is probably barely any slower. And it looks far better than the Cayman. Oh yes, and I'd be saving £10k in the process too. At a laughable £65k, the Cayman GTS looks massively overpriced for the privilege of driving something inferior.
